My invention relates to improvements in safety razors and refers particularly to safety razors of such construction as to prevent the removal or insertion of a blade without the assistance of special devices adapted for those purposes.

One, of the objects of my invention is a safety razor of such construction that a blade can not be inserted therein without the assistance of a blade-carrying device adapted for that purpose.

Another object of my invention is a safety razor of such construction that a blade can not be removed therefrom without the assistance of a blade-carrying device adapted for that purpose.

Another object of my invention isa safety razor of such construction that the insertion of a blade-carrying device therein will insert and properly deposit a blade therein, and that the withdrawal of said blade-carrying device Will Withdraw a previously deposited blade therefrom.

Another object of my invention is a safety razor of such construction that a `blade inserted therein will be firmly but removably attached to the guard member without `abutment of the top, or cap, member.

Another object of my invention is a safety razor of such construction that a; blade deposited and properly positioned on the guard member can not be conveniently removed therefrom without the assistance of a blade-carrying member adapted for that purpose'.

Another object of my invention is a safety razor of such construction that a blade may be readily and properly inserted and deposited upon a guard member without Contact with the fingersof the operator.

Another-object of my invention is a safety razor of 'suchv construction that a blade deposited upon a guard member can be removed without contact with the lingers of the operator.

It is evident that the safety razors of my invention possessing the above-mentioned attrilsutes, and many others which will be evident upon a consideration of my disclosures and deserptons herein, have many important and valuable properties over those in which it is necessary for the operator to handle the blades, frequently resulting in cutting the fingers; and, in

which the blade frequently becomes displaced due to the tilting, or canting, of the device durng the 50 blade-positioningA operation.

The particular form of a device of my inven- 40 tion as shown in Figures 1 to 12 comprises a guard member 3U having a plurality of extended teeth 3|, 3| upon each side thereof, the end portion 32 of the guard 38 being inclined downwardly as shown particularly in Figure 1, for purposes 45 to be described later.

The upper face of the guard 30 carries a plurality of spaced extended lugs 33, 33 and 33', 33', the lugs 33', 33 being undercut to retain a blade in a locked position, two longitudinal recesses, or slots, 34, 34' and a centrally positioned elongated opening 35. One end of vthe guard 30 has a recess 36, all of which are shown particularly in Figure 8.

A blade retaining mechanism is carried by the finder face of the guard 30 and comprises a trip movement upon a revoluble movement of the trip' bar 31.

A slidable member adapted to retain a blade upon, and release it from, the guard comprises the sides 4|, 4|, the end 42, and the end 43, the latter being extended into the arm 44 having the upturned end 45 extending into the slot 34. 'I'his slidable member carries two hooked blade retaining l members 46, 46 extending above the upper face 'of the guard 30 and slidable within recesses within the recess 36. These two members 46, 46 are normally retained in pressed abutment upon the end of the guard by the flat springs 41, 41. This slidable member carries also the hooked blade retaining member 48 extending through the slot 34 and above the upper face of the guard 30. This slidable member is slidably attached to the under face of the guard 30 by the bearing having the arms 39, 39 and the bearing 49 attached to the guard 30 by the screw 50.

Each oi the two upwardly extended lugs 33', 33 has an undercut 5i and the two lugs are c'arried by a member 52 which abuts upon the resilient member 49, and is normally locked by the end of the arm 53 of the slidable movable member, the lugs being movable through openings 54, 54 of the guard- 30, as shown. particularly in Figure 9.

The illustrated handle comprises a cylindrical member 61, the upper portion of which is internally threaded to mesh with the exteriorly threaded guard member 66, the lower end of the cylindrical member 61 being closed by the closure member 68. The lower portion of the cylindrical member 61 carries a revoluble sleeve 69, the closed end 10 of the sleeve 69 carrying the xedly attached cylindrical member 1|. which extends through the opening 12 of the end member 68 of the cylindrical member 61 and carries a xedly attached elongated at member 13, which is guided at its upper portion by a cylindrical member 13 within the sleeve 80.

My device includes a cap adapted to be capable of pressure abutment upon the upper face of a blade and to maintain it in fixed position between the guard and the cap for shaving purposes.

The cap illustrated in the drawings under consideration comprises a top member 14 having the two parallel longitudinal recesses 15, 15, which are so positioned as to receive the lugs 33, 33 and 33', 33' of the guard 30. Fixedly attached to the under face of the t: J member 14 is a centrally positioned downwardly extended member, the upper portion 16 of which is longitudinally shaped, its dimensions being such that it can be passed through the opening 35 of tno guard 30 when the longitudinal axes of the members 16 and 35 are parallel, and which portion 16 is not capable of being'passed through said opening when said longitudinal axes are not parallel to each other. Tne longitudinally shaped member 16 is extended into an elongated member 11 adapted to pass through the opening 35 of the guard 30 and into the cylindrical stud 66, the lower portion 18 of said member 11 being threaded. Co-acting with the threaded member 18 is the interiorly threaded revoluble cylindrical member 80, the lower endv portion 8| of which has the opposed longitudinal slits, or recesses, 82, 82 into which the longitudinal at member 13 is inserted.4 A coil spring 83 abutting upon the member 84 andthe loose washer 85 which abuts upon the upper face of the cylindrical member 80, tends to push the top member 14 upon a blade placed upon the guard.

The revolution 'of the sleeve 69, revolves the member 13 which in turn revolves the sleeve 80. If the revolution of the sleeve 69 is clock-wise, this revolution moves the sleeve 80 upwardly until the washer 85 abuts upon the lower face of the stud 66, a further movement drawing the cap 14 rmly upon a blade situated upon the guard 30 and maintaining itin position during a shaving operation.

able.

If it is desired to insert a new blade or remove an old blade, or both, the sleeve 69 is revolved counter-clock-wise, whereupon the sleeve moves downwardly, the washer is separated from the lower face of the stud 88, and the spring 83 will release its pressure of the top 14 from contact with the blade, and if this movement is continued as far as it will go, the sleeve 88 can be pushed up bringing the portion 18 of the vertically movable member above the opening 35 of the guard, the top 14 can be revolved, and if revolved a quarter turn the spring 83 and member 16 will retain it inl this open portion, which position is adapted for the ready washing of the device `as seen in Figures 11 and 12.

The form of blade adaptable for the described razor of my invention is shown in Figure 10 and comprises a blade of ordinary, or desired, thickness and dimensions having a longitudinal centrally positioned recess 88, four longitudinal openings 81, 81, and end recesses 88, 88 for purposes to be'described later.

One of the objects of my invention is a razor so constructed that it is impossible to insert or remove a free individual blade without the assistance of specially constructed devices particularly adapted for that purpose.

That a blade can not be introduced into or removed from the described device of my invention without the employment of specially designed devices is evident from a consideration of the following description.

Assuming that the device is in the normal condition -for shaving as shown in Figures 1 and 2, or in a condition with the cap 14 raised from the guard 30, the blade |00 is positioned upon the guard 30 with the blade retainingmember 48 extending through the slot 34 .of the .guard 30 and the recessl I9 of the blade, the hooked end being positioned upon the blade preventing its movement longitudinally in one direction as the member 48, as well as the hook members 46-48, is prevented from movement as long as the described slidable member 4| is rendered immov- The end portion of the blade is positioned between the blade retaining hook members 46, 48 and the lugs 33', 33' inserted in openings 81, 81 of the blade. The lugs 33', 33" are retained from downward movement by the abutment of the member 53 upon the lower portion ofl the bar 52 Further, the blade |00 isV 0f the lugs 33', 33'. positioned below the hook members 48, 48, which are also a part of the slidable member 4| and also below the undercut lugs 33', 33' which are carried by the guard, and hence it is evident that the blade |00 is retained from longitudinal movement in both directions and, further, is retained from vertical movement from the guard, asbest seen in Figure 12.

' ,The illustrated handle comprises a cylindrical member 81, the upper portion of which is internally threaded to mesh with the exteriorly threaded guard member 86, the lower end of the cylindrical member 81 being closed by the closure member 88. The lower portion of the cylindrical member 81 carries a revoluble sleeve 69, the closed end 10 of the sleeve 88 carrying the xedly attached cylindrical member 1| which extends through the opening 12 of the end member 88 of the cylindrical member 81 and carries a xedly attached elongated at member 13, which is guided at its upper portion by a cylindrical member 13' within the sleeve 80.

It is to be noted that even the raising' of the cap by revolution of the sleeve 89 will not release the blade, as the blade is firmly attached to the guard by the described mechanism carried by the guard.

That a blade can not be introduced into the described device of my invention Without special mechanism adapted for that purpose is evident from the following:

As a blade can not be introduced unless the cap is raised from abutment upon the guard, it is necessary to raise the cap from the guard and maintain it in that position during the insertion of a blade. Assuming, therefore, that the cap is raised from the guard and retained in that position during the attempt to introduce a blade. In order that a blade may be placed in abutment upon the upper face of the guard, the one edge of the blade must be beneath the hook-like members 48, 46, beneath the hook-like members 33', 33', beneath the hook-like member 48, and the projecting lugs 33, 33 of the guard must be inserted in the openings 81, 81 of the blade. A consideration of the drawings shows that such positioning is not possible. If a blade be moved inwardly in order that the member 18 o f the cap can pass through the opening 88 of the blade, the interior edge of that slot will contact the blade-retaining member 48 of the guard, preventing the further insertion-of the blade and there is not space enough between the hook-like blade-retaining member 48 and its adjacent lugs 33 of the guard to rlexA the blade beneath the member 48. Further, the edge ofthe blade must be positioned beneath the hook-likev members 48, 48, and the blade can not reach them, and even if it did pass the cap member 18, there is not space enough between the members 48, 48 and their adjacent guard lugs 33', 33' to flex the blade to accomplish the purpose. As it is evident that the guard lugs 33, 33 must be inserted within the blade openings 81, 81 in order to position the blade, this can not be accomplished for the reasons stated above. f In addition to the above-mentioned means for preventing the insertion of a blade without the employment of a special device, if the cap is positioned as shown in Figures 11 and 12, the width of the member 18 will prevent the 'insertion of a blade as it is wider than that of the blade slot 88. It is evident, therefore, that the employment of some device which will depress the trips 38, 38 is necessary in order o insert a blade.

In order to demonstrate that my device is operative, I illustrate and describe one form of a dcvice adapted for this purpose.

' Figures 13 to 18 illustrate one form of a device of my invention adapted for the insertion, and removal of blades into and from the razor of my invention previously described.

The particular form of my operating device shown in Figures 13 to 18 comprises a blade magazine adapted to receive a stacked plurality of blades. The top, sides and a portion of the bottom are formed by a Hat top member |0I, the sides of which are` bent upwardly and then outwardly to form the curved edges |02, |02, then downwardly to form the sides |03, |03, then inwardly to form the bottom members |04, |04, then upwardly to form the shoulders |05. |05 and then, inwardly to form the inclined blade guides |08, |08. The top' |0| has a longitudinal recess |08, the portion |08 oi' the top |0|, containing the rectangular recess |01 being inclined downwardly, thev outer edge of which is spaced from the inclined member |06 to allow of the passage of a blade therethrough. The lugs ||0, which are rectangular in shape are secured to the top |0| of the operating device. Positioned within the device is a leaf spring I I having the longitudinal recess II2 and the openings ||3, ||3 through the latter of which extend the lugs ||0, ||0. The spring III is riveted to the top |0| by means of the rivet I I4, and in normal position the two end extremities I I5, I I5 are resiliently pressed against the under face of the inclined member |06. A plurality of blades |00, |00 as shown in Figure 17 are stacked within the blade magazine, as shown, the recess 86 of the blades coinciding with the recess |08 of the top member |0| and the recess II2 of the spring with the lugs ||0, ||0 of the device passingthrough the holes 81, '81 of the blade. The blades are thus positioned in exact coincidence with each other within the magazine. The space between the faces of the lugs III), ||0 and the inner edge of the member |09 is less than the thickness of two blades, thus allowing of the passage of only one blade from the magazine, and the spring III forces the bottom blade of the stack in the magazine against-the under edge of the member |06 in position for withdrawal therefrom through the space between the members |06 and |09. The rear end of the magazine is closed by the member IIB. The two bottom members |04, |04 havetwo openings 204, 204 for purposes described later.

The method of applying the blade magazine shown in Figures 13 to 18 to the insertion and deposit of a new blade and the withdrawal of an old blade to the razor shown in Figures 1 to 12, is shown in Figures 19 to 24.

Figures 19 and 20 illustrate the first step of thus inserting a blade and withdrawing a blade and comprises raising the cap 'I4 from abutment upon the positioned blade |00 which itis desirous of removing from the razor. The inclined portion |09 of the magazine top |-0| is inserted between the inclined member 32 of the guard 30 and the blade |00, the blade |00 thus resting upon the upper face of the inclined portion |09 of the magazine top |0| and the magazine is` forced slowly inwardly. During thisv movement the shoulders |05, |05 of the magazine abut upon the shoulders |2I, |2I of the guard 30, thus guiding the magazine longitudinally over the guard.

This position is shown in Figure 20, from which it will be noted that the blade |00 is flexed and the end portion is upon the inclined members |09, |09 of the magazine, this flexing removing the blade from the blade-retaining member 48, that member, however, not being allowed to swing freely as the strips 38, 38 have not been moved.

Figure 21 illustrates a further inward movement of the magazine, in which the blade |00 has moved up further along the upper face of the inclined portions |09, |09 of the magazine. The trips 38, 38 have now been depressed by the bottom |04 of the magazine as it has passed over it, 'thus releasing the blade 'retaining member 48 and allowing it to be moved out of the way for the' passage of the magazine blades.

Figure 22 shows the complete passage of the magazine into the razor. The blade |001 is now positioned upon the upper face of the top |0|,

and the square lugs ||4, ||4 engage the recess I9 of blade |00, and the withdrawal of the operating device ycarries the blade with it. The trip 53 has now been depressed by the magazine causing the blade-retaining member to move outwardly .se that it will not interfere withthe lnsertion of a new blade. During this movement the magazine has carried the stack of blades inwardly and has positioned them properly above the guard. The lower blade of this stack has been pressed downwardly by the spring |I| allowing it to pass over the magazine lugs H0, I|0 and hence outwardly of the magazine,.while the remaining blades are prevented from such movement. The lugs 33, 33 of the guard now enter the openings 81, 81 of the lower blade, thus retaining the blade positioned upon the guard during the withdrawal of the magazine. During this withdrawal, the released trips 38, 38 and 4G, 46 move upwardly thus locking the blade-retaining memy guard without the employment of a cap to accomplish this result.

Figure 21 illustrates a further movement of the magazine, in which the blade |00 has moved up further along the face of the inclined membersA |09, |09 of the magazine and is now resting partially upon the member |0| of the magazine. The bottom members |04, |04 have now passed over the trips 38, 38 causing them to revolve into a depressed position as shown in this gure. This movement of the trips 38, 38 has moved the slidable member, thus causing a movement of the blade-retaining members 48, 46, 46, andreleasing the blade |00 from the guard.

Figures 22, 23 `and 24 show the complete insertion of the magazine with the razor. The blade |00 is now positioned upon the upper face of the magazine top |0| and the lugs H4, ||4 engage the recesses 81, 81 'of the blade |00 and the withdrawal of the magazine carries the blade |00 with it. vDuring th's movement the magazine has carried the stack of blades inwardly and has positioned them properly above the guard, and as the 4openings 204, 204 of the magazine inembers |04, |04 are now above the trips 38, 38, the

trips are pressed upwardly through the openings 204, 204 by means of the springs and hence return to their original position, thus moving the slidable member and. bringing the blade-retaining members 43, 46, 46 into the original bladeretaining position, with the blade |00 beneath the hooked ends of these members and below the undercut lugs 33', 33', of the guard which have entered two openings 81, 81 of the blade |00', the guard lugs 33, 33 having entered the other two openings 81, 81 of the blade |00'. During the withdrawal oi' the magazine, blade |00 remains upon the guard and when the magazine is fully withdrawn the blade-retaining members retain the blade upon the guard in such manner that the blade cannot be removed except by means of a specially constructed device .as is shown in the magazine thus described. During this withdrawal movement the old blade |00 is withdrawn by and upon the upper face of the magazine top |0I.

The modied form of my device illustrated in Figures 25 to 44 is `adapted for use with single edged bladesand its operating mechanism of the handle and cap is identical with that described in connection with the form of my device shown inFigure 1 and its accompanying drawings, -it is believed that it is not necessary to describe it again, and, therefore, the same numerals are 75 -blade-retaining members 322, 322, 320, 3|6, 3|6

employed in the description of this form of my device as are employed in the first described form.

For purposes of clarity, the modied elements of this form of my device carry numerals commencing with the number 300.

This form of my device comprises a cap 300 having the recesses 30|, 30| in the under face thereof, this cap .being riveted, or otherwise xedly attached to the member 16 of the handle mechanism, which allows the cap to be raised from contact with the guard, or a blade positioned upon the guard, as shown in Figure 34.

The guard 303 has a plurality of teeth 304, 304 extending fromv one side thereof, the side portions 305, 305 of the guard being lower than the face of the central portion, thus forming the shoulders 306, 306. The guard 303 has two forwardly positioned aligned elongated openings l301, 301, two centrally positioned aligned elongated openings 308, 308, a centrally positioned elongated opening 309, and two corresponding recesses 3|0, 3|0 in its rear portion. The guard has aslo an opening 3| I, of such size and shape as to allow vertical movements of the member 16, when the edge of the cap is parallel to the edge of the guard, but will prevent such movements when the edge of the cap is in angular position to the edge of the guard.

The depressed portions 305, 305 of the guard have the elongated openings 3|2, 3|2. v

The central portion 3|3 of 'the underside of the guard between the two end iianges 3|4, 3|4 is depressed in order to allow the insertion of slidable operating elements therein, the face of said slidable elements lbeing substantially ush with the tace of the anges 3M, 3|4.

Fixedly attached to the under vface of the guard are two flat springs 3|5, 3|5, each carrying a blade-retaining member 3|6 extending through an opening 308.

The slidable operating member, as shown particularly in Figure 33 comprises the base mem-- ber 3|1, xedly attached to the under face of the guard by means of the plates 3|8, 3|6 which act also as bearings for a trip member to be described later. This slidable member has two upwardly extended studs 3|9, 3|9, a centrally positioned extended hook-shaped blade-retaining member 320 and two `arms 32|, 32| each having an extended hpok-shaped' blade-retaining member 322 and an inwardly extended arm 323.

A tripping mechanism comprises the bar, or rod, 324, revoluble within the bearings 3|8, 3|8, the rod 324 carrying the two cam members 325, 325 and the ends 326, 326 of the rod 324 being bent upwardly.

Two flat springs 321, 321- are carried by the guard and abut upon the slidable member, thus tending to move the slidable member forwardly toward the front of the device, any rearward movement of the slidable member being against the tension of this spring.

When the deviceis in its normal position, as shown particularly in Figures 25, 27 and 28, the blade-retaining members 322, 322 extend through the recesses 3|0, 3|0 of the. guard, the

blade-retaining member 320 extends through the opening 309 of the guard, the cams 325, 325 of the tripping rod 324 abut upon the lugs 319, 3|9 of the slidable member, and the arms 323, 323 of the slidablev member cover the springs 3|5, 3|5

thus preventing the downward movement of the blade-retaining members 3|6, 3|6.

When the device is in this position, all of thel are extended above the upper face of the guard and can be released or depressed only by a movement of the tripping device.

If now the two trips 326, 326, which extend through the openings 3|2, 3|2 of the guard, be moved rearwardly, the rod 324 will revolve, the cams 325, 325 abutting upon the studs 3|9, 3|9 will move the slidable member rearwardly, thus moving the blade-retaining members 322, 322 and` 320 rearwardly, =and allow the depression of the blade-retaining members 3|6, 3|6.

In Figure 30 I show one formof a one-edged blade 328 suitable for use in the razor just de-v scribed, and which has two openings 329, 329, adapted to receive theblade-retaining members 316, 3|6 and the recess 330 adapted to receive the blade-retaining member 320.

A consideration of Figures 27 and 28 will illustrate the means whereby the blade 320 can be removed, or a new blade introduced, only by the movement of the trips 326, 326.

VOne form of .a 4device of my invention adapted to remove an old blade, or insert a new blade, or to perform blade operations at the same time, is illustrated in Figures 36 to 39.

This device is one which acts as a blade holder, a blade ejector and a blade remover, thus possessing all the necesary functions for removing an old blade, depositing a new blade and fastening the new blade into position for shav- This particular form of a device of my invention comprises the top member 33|, extended into the two side flanges 332, 332, and the rear flange 333, the sides being bent downwardly 334, 334, thence inwardly i335, 335, inclined upwardly, 336, 336 and thence inwardly 331, 331, 331', 331'. The front portion 338 of the top 33| being inclined downwardly and spaced from the members 331', The top member 33| has the recess 338', and two upwardly extended lugs 339, 339.

The inclined portion 338 carries two resilient metalled fiat arms, or projections 34|, 34|.

A iiat spring 342 is riveted to the under face of the top 33| and is pressed by its resiliency against the under faces of the members 331', 331', the

spring having openings 342', 342 through which the lugs 339, 339 carried by the top 33| extend. Each member 331 has an opening 340 for purposes described later. A plurality of stacked blades 328, 328 is placed between the spring 342 and the members 331', 331.

The operation of the above-described blade magazine ejector with the described razor is shown in Figures 40 to 44.

In Figures 40 and 41, the resilient fingers 34|, 34| of the ejector have been introduced beneath the old blade 328', and as the ejector is moved inwardly as shown in Figure 42, the old blade has moved upwardly over the fingers 34|, 34|, the trips 326, 326 have been moved rearwardly, thus moving the slidable member and releasing the blade retaining members carried thereby. At the same time, the new blade 328 is being positioned upon the guard.

In Figures 43 and 44, the ejector has been introduced to its full extent, the old blade 328 is positioned upon the top' of the ejector with the ejector -lugs 339, 339 extending through the openings 329,

moving the blade-retaining members into positions retaining the blade in position.

My invention, therefore, presents safety razors so constructed that the insertion and removal of blades by hand is practically impossible while the insertion and removal of blades is easily and effectively accomplishedby devices adapted for that purpose and especially by blade magazines as shown and described.

Many changes may be made in the unessential elements of the devices, as shown, without'going beyond the scope of my invention; the wellknown spaced bar guards may be employed instead of toothed guards, the cap may be hinged to the guard, separable therefrom or otherwise attached thereto and other evident changes of parts may be employed.

Therefore, I do not limit myself to the particular form, size, number or arrangement of parts of the razors and devices as shown and described as these are given simply as means for clearly describing my invention and may be varied and changed Without going beyond the scope of my invention.
